title: Intraesophageal balloon distention in the manometric evaluation of chest pain.
abstract: Drug provocation is routinely used during esophageal manometry in the evaluation of chest pain of presumed esophageal origin. As significant side effects have been associated with the use of drugs in provocation, and these provocative tests are inadequately sensitive to exclude esophageal etiology as the cause of chest pain, alternative provocative tests have been sought. Intraesophageal balloon distention (IEBD) has recently been reintroduced as a method of pain provocation in the manometric evaluation of chest pain. IEBD produces pain on distention which resolves immediately on deflation. To evaluate graded IEBD as an effective and safe method of pain provocation, 66 consecutive patients presenting with chest pain and 10 asymptomatic volunteers were studied. We conclude that balloon distention is an effective and safe method of pain provocation and can easily be performed in conjunction with standard esophageal manometry.
